Description of manufacturing Hot Dip Galvanized Gratings

1. Fully-automatic welding machine of high frequency is used to manufacture hot dip galvanized gratings and cover (except edge welding/ banding) in order not to trigger any melting corrosion on the base material.

2. Material: CNS SS400 steel

3. Surface Treatment: After grating is formed, the surface is treated by hot dip galvanization; the thickness of galvanization is 610g/m².

4. Edge Welding: Two edged sides of gratings are welded with H*6mm flat steel. Welding slag will be removed cleanly.
